Well I'm too lazy so this'll be a cherry Lemon (a cherry lemon is where there is little to no backstory)
DISCLAIMER:
iconnotforhire and I have created the classification for Cherry Lemons and any future classifications I mention in the future. The two of us would like to be given credit for these classifications if used in your books.
Thank you.
Enjoy the lemon!

Kokona pinned Saki to a wall of an empty room of the school with a single instrument case at the back. Strange, neither of them knew about this room. After all Kokona did chose it out of random. Nobody but the students in clubs were here and clearly they were nowhere near them.

Saki gasped as she was pinned to the wall. She had no idea Kokona senpai had feelings for her. She had only dreamed about this..... A few times. Saki wasn't the type of girl to go Yandere; that was Yandere-chans job. Kokona slammed her lips into Saki's, yet kissed her softly at first. Saki happily accepted the kiss from her senpai and kissed back. As they kissed things got more heated, the kissing escalated into a make out session against the wall. Kokona licked Saki's lower lip asking her for an entrance. Saki happily opened her mouth for her senpai.

Once her mouth was opened Kokona slid her tongue inside. Her tongue explored the new space before they engaged in a tongue battle. Their tongues danced around in a battle for dominance; of which Kokona won. As their kissing continued Kokonas hand snaked up Sakis shirt and under her bra. She began massaging Saki's huge left mound. Her warm palm rubbed against the nipple. As she did this a soft moan exacted the eager Saki as she wrapped her leg around Kokonas waist. As Kokona continued to do this the more eager Saki got. Kokona took her hand out from Saki's shirt and bra. She then quickly pulled her shirt off. Saki helped her by pulling her long pigtails through the neck hole of her shirt. With that she took off Everyones Favourite Punching Bag's shirt and tossed it to the floor as Kokona tossed Sakis shirt to the floor too.

They slammed their lips into each others own, picking up from where they had left off. As the kissing continued they both slid their hands up each others back removing each others bra. They unclipped each others bra, letting them plummet to the floor at their feet. The bras were soon forgotten as their skirts and panties came off. Kokona broke the kiss and made her way over to the instrument box. Saki watched her, confused and rather curious. "What's senpai doing?" She thought as she watched Kokona open the instrument box.
"Thank god I made a deal with Info-chan. Taking those pantie shots were worth it." She thought as she reached inside and pulled out a teal coloured toy. She made her way back over to Saki. She grabbed Saki and pulled her arm down. Catching on Saki sat down on the floor, spreading her legs open. Kokona held the toy and leaned in after scooting closer on her knees.

She slid her tongue through Saki's folds and up to her clit. Once Kokonas soft tongue slid over her clit, a soft moan escaped the now blushing Saki. A faint giggle was heard from Kokona as her tongue continued to slide around. Eventually Kokona found Sakis entrance and slid her tongue inside and leaned in closer. Sakis moans had gotten louder since Kokona had started and they were only gonna get louder. Bitchy-chans tongue explored the new space. As Kokonas tongue swirled around Sakis moans only got louder. Kokonas tongue slid over Sakis sweet spot. Saki moaned loudly, bucking her hips pushing Kokona's tongue in deeper. Kokona giggled, continuing this action. Eventually she removed her tongue from Saki. With that Saki scooted forward and pinned Kokona down. She stuck her finger into Kokona. She pushed and pulled it in and out. Kokona moaned. She wanted to take her dominance back but for now Saki wasn't gonna allow that. One finger turned into two, two fingers turned into three. With that Kokona's moans got louder. At That Kokona grabbed the toy and shoved it into Saki. Saki gasped. Kokona pushed the toy into Saki. Once it was in she quickly pulled it out and pushed it back in. Continuing this Saki stopped moving her fingers and they slowly slid out of Kokona.

Kokona reasserted her dominance and sat up taking Saki with her. She pushed Saki down and started pushing and pulling the toy. Saki moaned loudly. Kokona pushed and pulled faster and faster until she was pushing and pulling as fast as she could. Saki's moans got louder and louder. "Kokona senpai I... I'm gonna cum." Saki moaned tilting her head back. Kokona smirked and continued her actions. Saki moaned arching her back letting her fluids spill out onto Kokona's hand. "I'm glad to hear I'm your senpai because I'm your Yandere." With that Kokona tranquilized Saki and clothed herself and Saki before stuffing her in the instrument case. Kokona walked home and locked Saki in her basement before going to bed.
